Question about 2003 Oldsmobile Alero
I OWN a 2001 Olds Alero and the same thing happens to mine.. It's an easy fix..
1. Turn the Key to ACC (keep it in this mode for the entire 10 minutes).
2. The security light on the Dashboard will flash for exactly 10 minutes..
3. Once the 10 mins are over, the security light will stay solid..
Wait for the red light to disappear off the dashboard...
YOU ARE NOW READY TO TURN YOUR CAR OFF AND RESTART YOU CAR....
I DO THIS ALL THE TIME TO MINE..

Turn the key to the on posistion (don't try to start it) leave it on for about 10 minutes or until the security light stops flashing. Turn the key off for a second or 2. It should start now. The problem is the body control module. It can be replaced or bypassed/overridden with instructions found on the internet. Hope this helps.

There isnt a fuse for the theft system. You need to take the coloum cover off. Should be 3 screws and you will see all the wires in there. The ones you need are three togather. White Black and Yellow. Get the car started and cut the yellow wire. The theft light will come on and stay on but will bypass the theft system. If it is a 2 wire system you will see two little metal strips on the upper side of the key. You have to use a ohm meter and measure the resistance of the strip in there. Its a resistor used to tell the theft computer the key is in there. Anyway find out what the resistance is and buy a resistor from radio shack and look under the steering wheel for the 2 very small guage wires in a yellow cover....NOTE not the air bag wires. Simply cut those wires ( the 2 white ones) and on the set going away from the steering wheel strip the wires and put the resistor one one wire and the other end of it to the other wire....That will disable that system. If its the 2 wire and you have issues getting it simply take the car to a car audio place that does remote starts and for a nominal fee they will do it for you. My records show that it has the 3 wire system.

With the new lock cylinder in it, turn the key on. The security light should blink. Leave the key on for 10 minutes, the security light will quit blinking and go out after 10 min. This will reprogram your security system and the car should start. Also leave a battery charger on it while the key is on, If the battery goes dead during the 10 minute reprogram sequence, you will have to start over again.

HI there if the scan tool you are using will not reprogram the theft module the try the 10 min relearn

The security system is activated. It kills the injector pulse ( signal) and on some modles the starter. You will need to try to relearn the system. First try to start the car, leave the key in the run position for 10 minutes. Cycle the key off, then cycle it to the run position again for 10 more minutes. Cycle it off again, then back to run for another 10 min. after the last cycle turn it off then try to start the car. It is a 30 minute relearn. If this does not work you will need a repair shop to replace the passlock sensor. Good Luck

Testimonial: "it was in the ignition and the security activated i had to replace the whole igintion key and all "
If the previous solution doesn't work, try this:
While the key is in "on" position and your security light is blinking, it is probably your "Passlock" security device acting up. Very common in these years for GM cars. To test if this is it, simply turn your key forward (to "on" position) until light stops blinking and eventually turns off (right around 10 minutes). Then, turn key back off, and then try to restart it. My Alero did this just a few months ago and I learned this trick as I was pricing out a new fuel pump. If this was your problem, I recommend taking it to a remote starter installer and have them by-pass the passlock system permanently. This should cost anywhere from $40-$100, but is much better than a new fuel pump and filter cost.
-note: I recommend not getting it by-passed until it happens a second time (which it may not), just don't forget the temporary fix!
